Differentiated tagging is needed for differentiated rendering.  "junction" vs "Signal". a single signal icon needs to be rendered in Japan for intersections.

is there a way to tell the renderer to not render it's icon if it is part of another area's way? that would allow the intersection tag to take over for the rendering of the signals for it's single icon.  

if that's the case:

landmark=intersection  ?
Intersection=signals for Japan, intersection=junction for korea, or other named junctions.
